CLOSET-CISTERN.

SPECIFICATION forming part of Letters Patent No. 447,534, dated March 3, 1891.

Application tiled October 27,1890. Serial No. 368,491, (No model.)

To all wiz/0771, t may concern:

Be it known that I, BYRON R. BACON, a citizen of the United States, residing at East Orange, in the county of Essex and State yof New Jersey, have invented an Improvement in lVater-Oloset Cisterns, of which the following is a specication.

Tater-closet cisterns have heretofore been made with a siphon, which in some instances 1o has been stationary, and in other instances it has been connected with a moving valve, the Siphon serving to draw the contents of the cistern into the flushing-pipe until the water passes below the end of the siphon. In these cases, however, the valve after it has been raised by the action of the pull descends by gravity *spon the seat.

In my present invention the valve is held up by a suction action produced bythe descending column of water, and the valve falls upon its seat after the contents of the closet have escaped through the iiushing-pipe and the air has been admitted into the suctionpipe to stop the action that holds up the valve.

In the drawings, Figure l is a vertical section of the improved cistern-connection. Fig. 2 is a similar view in a modified form, and Fig. 3 is a diagram ofthe device with two valves in place of a double valve.

The flushing-pipe A passes to the closet from the bottom of the cistern B, which cistern is to be of any usual or desired character, and of a proper size to contain water for flushing the closet, and the water is to be supplied to this cistern by a valve and float or ball, as usual, and at the upper end of the flushingpipe Ais a valve-seat 2, and the valve C, in its normal position, rests upon this seat 2, and there is a suction-pipe D, the long leg 3 of which passes below the seat 2, and the short leg 4 is formed at its lower end with a valveseat 5, and there is any suitable lifting device to act upon the valve.

In Fig. 1 the lifting device isrepresented as rods 6 to the crossheads 7, upon which the pull-lever acts, a portion of the pull-lever being shown at E, and in Fig. 2 the rod 6 is represented as connected directly to the pull-lever without any cross-head, and in this Fig. 2 the valve C is represented as pi-voted at 8, and the suction-pipe D as bent with the seat 5 at an inclination, so that the valve C will rest properly against either the seat 2 or the seat 5. In Fig. l the short leg` of the suctionpipe is represented as a larger tube surrounding the longer leg 3, and the seat 5 is parallel to the seat 2.

- In both forms of my apparatus the water passes from the cistern directly through the flushing-pipe A as soon as the valve O is raised, and when this valve is raised its upper face rests against the seat 5, and it is preferable to cover both faces of the valve with leather or similar flexible material, and the rush of water down the flushing-pipe A produces a powerful suction in the pipe D. Hence the valve C is held firmly against the seat 5 by atmospheric pressure, and it cannot descend upon the seat 2 as long as the water is rushing away from the cistern; but as soon as the water passes out of the cistern and the atmosphere passes into the pipe D the pressure is equalized and the valve relieved from the minus pressure or suction action, and such valve falls upon the seat 2, closing the outlet of the cistern, so that the cistern fills with water, as usual.

When the apparatus is constructed in the form shown in Fig. l, the valve is in the shape of a ring, and it is necessary to provide a seat for the inner edge of the valve as well as the outer edge, both at the seat 2and the seat 5. These are represented as formed by collars or tubes around the long leg 3 of the Siphon. I however do not limit myself to any peculiarity in the construction of the valve or its seat, and in Fig. 3 the valve is represented as in two parts O and C, and they `are connected to the pull-lever E at oppositeA sides of its fulcrum, and the suction-pipe D is not bent over, but stands upright, so that the valve C rests upon the top end thereof. In this position the valve O is held to its seat by atmospheric pressure in consequence of the minus pressure in the pipe D, and the valve O cannot close until after the atmos` pheric pressure is equalized by air passing into the flushing-pipe A.

I claim as my inventionl. rlhe combination, with the closet-cistern and the flushing-pipe, of a stationary suctionpipe Opening at its lower end into a iiushing- IOO lower end beneath the valve-seat and having a secondary Valve-seat at the other end against which the valve closes and is held during the I5 passage of the water from the eistern by the suction action, substantially as set forth.

Signed by me this 24th day of October7 1890.
